The high-temperature sterilization device uses pure superheated steam as the sterilization medium to rapidly sterilize and dry the granule powder, which is one of the ideal equipment for pharmaceutical enterprises to sterilize and dry the raw materials of traditional Chinese patent medicines and simple preparations products containing raw drug powder. It has energy-saving, high-efficiency, safe, reliable, economical, and maximizes the natural medicinal properties of the original powder.
UHT, also known as Ultra High Temperature Instant Powder Sterilizer, has the following sterilization principle:
The liquid material is preheated by being pumped into a double coil through a feed pump, and then passes through a high-pressure drum. Due to the steam filling in the drum, the liquid material inside the pipe is quickly heated. After being held for more than three seconds, the bacteria contained in the liquid material are immediately killed. At this point, the temperature of the liquid material can be displayed on the thermometer. After the hot material is discharged from the high-temperature barrel, it is cooled by heat exchange with the cold material through a double set of coils, so the discharge temperature can be significantly reduced, generally below 65 ℃. If some materials need to be supplied with higher temperatures in the next process, the angle shut-off valve can be opened to supplement heating. If further cooling is required, ice water (1-2 ℃) can be connected, and the discharge is carried out through a throttle valve. This valve can maintain the material under a certain pressure, so that its boiling point is higher than the higher heating temperature. During normal production, it is adjusted, and the flow rate is controlled by the thrust of the pump to overcome the "back pressure" generated by the spring pressure. It is fully opened during washing, and the circulation storage tank can be used to prepare chemical detergent for circulating and washing the fouling on the wall of the coil.
